If you’ve got a modern TV that’s hooked up to the internet, chances are you’re familiar with TV Aerials. What are they and how do they work? Essentially, a TV aerial is simply an antenna specially designed for in use on a TV receiver to receive over the air broadcast TV signals from another television station. This can be done in a variety of ways. Most television aerials use a cable assembly that is suspended above the programming source (usually behind a set top unit) and an unobtrusive rectangular box shaped like a manhole hatch sits atop the TV aerial.
TV aerials differ from conventional TV because they broadcast digital TV signals instead of analog TV signals. Analog TV signals are the old-fashioned kind of TV signal that television stations used to broadcast back in the 40’s and before. They were less than clear and had a tendency to switch from channel to channel which made watching a program more difficult. Today, most satellite companies offer digital TV channels which are much clearer and require only a very narrow picture plane so the quality of the picture is much better than it was in the old days.
When choosing TV aerials for your home situation, there are a few factors that you should consider. The primary factor is the amount of receiving power that your TV has since many aerials will only pick up a limited number of channels. Your second biggest factor will also have something to do with how clear the picture can be and how strong the signal is for the frequency you choose. For instance, if you have a satellite dish network installed in your home, you’ll need to choose a TV aerials frequency with enough power to handle the satellite feed. You can find TV channel frequencies in the TV charts offered by many of the satellite companies but the best way to find out what they are is to ask someone with experience and who knows what kind of TV aerials will work best in your home situation.
